Any suggestions for addressing this issue would be greatly welcomed. Thank you.Re: Black Tank QuestionNewbie: Great idea! I fill my tank about 1/3 full after each empty and add Tide detergent to black and grey water tanks. The movement of your unit as you drive down the road will act just like that of a washing machine. I cannot think of a better way of cleaning your tanks. DaveRubber Roof RepairI have noticed some bubbling on the rubber roof of my 5th wheel about the size of a half dollar. Is this normal or is this the beginning of a major issue. I'm told that this is caused by a vacuum created by the wind sucking the roof upwards as you drive down the highways. Is there a preferred or recommended repair method? After much thought, I am considering making a small incision in the bubble area and injecting Dicor Sealant until the bubble area is full and starts to ooze out which would also reseal the initial incision. Is this a good approach for repairing these small bubbles or should I even worry about it? Looking for opinions and suggestions. Thank you. Dave
